Localized haptic feedback

Abstract

A surface that generates a haptic feedback includes a first region having a first level of stiffness and a second region having a second level of stiffness that is less than the first level of stiffness. The second region defines a deformation region within which the haptic feedback is generally localized.

Description

technical field [0001] One embodiment of the invention relates to tactile feedback. More specifically, one embodiment of the invention relates to localizing haptic feedback to specific regions. Background technique [0002] Humans interact with electronic and mechanical devices through interfaces in many applications, and the need for more natural, easy-to-use, and informative interfaces continues to receive attention. In the automotive environment, the dominant interface is still mechanical buttons or dials. One reason for the popularity of such interfaces is that motor vehicle drivers often must manipulate buttons or dials while still watching the road. Mechanical devices make the driver feel mechanical buttons or dials. [0003] However, using mechanical buttons and dials has several drawbacks. First, any type of mechanical interface is subject to wear and degradation. Second, the buttons and dials on the dashboard of a motor vehicle include slits and crevices where ...

AI Technical Summary

Problems solved by technology

[0003] However, using mechanical buttons and dials has many disadvantages

First, any type of mechanical interface is subject to wear and degradation

Second, the buttons and dials on the dashboard of a motor vehicle include slits and crevices where dirt can collect and thus become unsightly and unsanitary

However, known haptic feedback devices often fail to isolate the feedback (i.e., vibration) within the boundaries of a particular "button"
